What this PMI calculator does

This calculator finds your monthly PMI on a home loan. You enter the price, your down payment, and a rate. The tool then works out the monthly cost. So you see what PMI adds each month. It applies when your down payment is small. The result is shown in your currency.

What PMI is

PMI is private mortgage insurance. It protects the lender if you stop paying. You pay it, but it does not cover you. Lenders require it on low down payments. So it is a cost of buying with less cash. It falls away once you build equity.

How it is calculated

The tool finds your loan amount first. It is the price less your down payment. It applies the yearly PMI rate to the loan. It then splits that into a monthly cost. The result is your monthly PMI. The calculator works it out for you.

What the result tells you

The result shows your monthly PMI. A loan of three hundred sixty thousand at half a percent costs one hundred fifty a month. A bigger loan raises it. A higher rate raises it too. So it shows the monthly insurance cost. It is a rough estimate only.

The home price

The home price is the value of the home. It sets the size of your loan. A higher price means a bigger loan. So it lifts the PMI you pay. Use the agreed purchase price here. It drives the entire result here. Enter your home price.

The down payment

Your down payment is a percent of the price. A bigger down payment shrinks the loan. It also lowers the PMI you owe. So more cash up front helps twice. At twenty percent, PMI usually drops away. So a larger sum can remove it. Enter your down payment.

The PMI rate

The PMI rate is a yearly percent of the loan. It often runs from a third to one percent. Your credit and loan type affect it. So a stronger profile means a lower rate. The tool applies the rate you enter. A higher rate lifts your monthly cost. Enter your PMI rate.

The twenty percent mark

PMI is tied to your loan-to-value. That is the loan as a percent of price. Above eighty percent, PMI usually applies. So a down payment under twenty percent triggers it. Once you reach that mark, PMI can stop. Paying down the loan helps you get there. Rising home value can also help.

How to use it

Enter your home price first. Add your down payment and PMI rate. Read the monthly PMI in your chosen currency. Then try a bigger down payment. See how the cost drops. Compare a few rates. Use it to plan your budget.

How to remove PMI

You can drop PMI over time. Pay the loan down below eighty percent of value. Then ask your lender to remove it. A new appraisal may help if value rose. Some loans drop it for you at a set point. So track your balance against the home value. Removing it lowers your payment.

A final tip

Use this to see the cost of a low down payment. Remember PMI protects the lender, not you. A bigger down payment can avoid it. Watch your loan-to-value over time. Ask to remove PMI once you qualify. Do not pay it longer than needed. A careful plan saves you money.

Frequently asked questions

When do I pay PMI?

Lenders charge PMI when your down payment is below 20%, so the loan is over 80% of the home's value. It protects the lender, not you.

How do I get rid of PMI?

PMI usually ends once your loan falls to 80% of the original value, either by paying down the balance or as the home appreciates. With 20% down there is no PMI at all.
